Laptop screen turns black

Hello
when I work on my computer Toshiba Satellite A215-S5818 sometimes the screen goes black (grey), you can hear that it's on but it doesn't respond to anything. I take out the battery and then switch it on again. Then it says that windows has not been closed correctly. Can you solve my problem?

In Windows XP you can disable hibernation by doing the following:
1. Open Power Options in Control Panel
2. Select the Hibernate tab
3. Clear the checkbox for enabling hibernation
This doesn't work in Vista however because the GUI for Power Options has changed and doesn't offer the ability to disable hibernation. But you can disable hiberation in Vista from the command line if you use admin privileges. Here's how:
1. Press the WINDOWS key and type cmd into the Start Search box but *don't* press ENTER
2. Right-click on cmd in the Programs list and select Run As Administrator
3. Click Continue when the UAC prompt appears
4. Type powercfg -h off and press ENTER

his is sound as though your power adapter is not charging your laptop battery and the battery is trying to preserve what power it has left to power up the screen as you demand but there is no voltage to do so. 1. you will need another power supply adapter from what you have describe here and or a battery replacement.if you can possibly get an equivalent power adapter for your unit and connect it to see if you get power up then you need to replace the power adapter.I hope this helps. Have a great day!

Sometimes my laptop does this as well. It seems to happen more and more when it is warm. You might try putting something underneath it and ensure it is getting enough air flow. Once I started doing this, mine has been doing it less and less. Hope this helps. Thanks, Ben

hi there I think you have picked up a virus which has secured your operating system.even safe mode cannot be run it for u to retrieve your data.give your machine a fresh installation. get and install a data recovery program and run fornated recovery for your data. if you have a recovery disk for your computer, you can use it for the reinstallation.thanks

thank you for your response....I'm using Vista and the power seems to be on but the screen is down. I have to hold the power button down for 10 seconds to shut down then turn it back on to restore the computer. It is a Toshiba A215-S5818
